Overview of this book

<p>Tkinter is the built-in GUI package that comes with standard python distributions. This means it is easy to get started right away, without any extra installation or configuration. Tkinter’s strength lies in its simplicity of use and its intuitive nature which makes it suited for programmers and non-programmers alike. Once you get started, you will be surprised to see how a few lines of code can produce powerful GUI applications.</p> <p>Tkinter GUI Application Development Hotshot helps you learn the art of GUI programming—building real-world, productive and fun applications like text editor, drum machine, game of chess, media player, drawing application and many more. Each subsequent project builds on the skills acquired in the previous project. Also, learn to write multi-threaded and multi layered applications using Tkinter. Get to know modern best practices involved in writing GUI programs. Tkinter GUI Application Development Hotshot comes with a rich source of sample codes that you can use in your own projects in any discipline of your choice.</p> <p>Starting with a high level overview of Tkinter that covers the most important concepts involved in writing a GUI application, the book then takes you through a series of real world projects of increasing complexity, developing one project per chapter. After you have developed five full projects, the book provides you with some bare-bone skeleton codes for a few functional but incomplete projects, challenging you to put your skills to test by completing them.</p> <p>Finally, you are provided with tips for writing reusable, scalable, and quality GUI code for larger projects. The appendices provide a quick reference sheet for Tkinter.</p>

Structuring our drawing program


Let's now get down to setting the basic structure for our drawing program. We want to achieve a structure, as shown in the following screenshot:

The structure here primarily consists of a top menu, which inherits from the GUI framework build_menu method that we created in the last iteration.

In addition, we create a top-bar frame towards the top(marked in yellow) with a method, create_top_bar(), and a toolbar frame to the left (marked with dark grey background) with create_tool_bar(). We also create a Canvas widget on the right side using the create_drawing_canvas() method, which is to serve as our drawing area.

We will not be reproducing the code for making the frames and canvas area, because we have done similar things in our previous projects and you should be comfortable making them by now. However, you can check the actual code in the file, 6.01.py.

Step 1 – importing framework

The first thing to note here is that we import our previously created...
